WHAT WE BUILT · OPEN SOURCE
southbridge.ai/hankweave
DOCS
hankweave.southbridge.ai
Because we use
hanksX — AI programs that separate concerns — a shared abstraction the team uses ,
broken into reusable
codonsY — sequenced units of work — separable units of work ,
watched by sentinelsZ — real-time monitors — something watching as it runs ,
with logsW — that humans actually read — that someone actually reads ,
shared and version-controlledV — so fixes accumulate — a surface that forces fixing over remaking .
